Molding Machine with Adjustable Wheel Rollers

ABSTRACT

The present invention relates to a household toy molding machine with adjustable wheel rollers comprising a frame, wheel rollers mounted on a frame, a transmission mechanism, a gear of the transmission mechanism connected to a gear of the upper roller and two gears occlusive together to drive the upper roller running then to drive the lower wheel roller for relative operation, wherein the two ends of the wheel roller are fixedly connected with the frame through a bearing; the lower wheel roller as an adjustable wheel roller is constituted by an outer roller, an adjustable wheel core and a bearing; the outer roller is arranged outside the bearing and the adjustable wheel core passes through the bearing center; both ends of the adjustable wheel core are connected to the frame with an adjustment knob connected with the adjustable wheel core arranged on the outside of the frame.

FIELD OF THE INVENTION

The present invention relates to a household toy molding machine,particularly a molding machine with adjustable wheel rollers.

DESCRIPTION OF PRIOR ART

The toy papers of existing DIY-molded toys, for processing and moldingat the same time, a molding and hot stamping machine is provided in theprior art which cannot be accommodated with the conventional moldingmachine; in the conventional processing equipment, the mouldssuccessively pass between the two rollers; however the existingdouble-roller is mostly fixed which has a big flaw; due to large amountof assembly parts and the connection errors between the various parts,the product pressed out will be under expectation, or due to thethickness of the mold itself is difficult to control, the stamping ofthe product will be uneven.

There is another situation in the prior art, if we want to make two setsof products of different pattern depth with a set of molds, it is unableto be achieved with the existing molding machine. At present, due todifferences of the market and diversified demand of people for thequality and function of the product, there is an urgent need for anadjustable molding machine.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a molding machinewith adjustable wheel rollers to control the pattern depth of productsby adjusting the distance between the two rollers to correct the errorsof the machine.

In order to achieve the purpose above mentioned, the present inventionis described like this: a molding machine with adjustable wheel rollerswhich comprises a frame, wheel rollers mounted on a frame, atransmission mechanism, a gear of the transmission mechanism beingconnected to a gear of the upper roller and two gears occlusive togetherto drive the upper roller running and upper roller driving the lowerwheel roller for relative operation, wherein the two ends of the saidwheel roller are fixedly connected with the frame through a bearing; thesaid lower wheel roller as an adjustable wheel roller is constituted byan outer roller, an adjustable wheel core and a bearing; the said outerroller is arranged outside the bearing and the adjustable wheel corepasses through the bearing center; both ends of the adjustable wheelcore are connected to the frame with an adjustment knob connected withthe adjustable wheel core arranged on the outside of the frame. Adoptingthe way of rotation of a single roll and driving the rotation ofauxiliary wheel, the method is simple and practical by simply adjustingthe up-and-down motion of the lower roller to meet the needs of thedistance change between the two rollers.

Further, the said adjustable wheel core is a mandrel whose both ends areeccentric shafts; the said bearing is a unidirectional needle rollerbearing which rotates in the opposite direction of the material feedingof the mode. Adopting the eccentric shaft, this technical solution issimple and the distance is unified by adjusting the height of eccentricshaft to adjust the distance between the two rollers. The adoption ofthe bearings of the invention has been considered that when simply usingordinary bearings, the device can only be used for molding and stampingsome products which are alternative, not too thick; when molding andstamping some products which are thick or having the request of deeppatterns with the ordinary bearings, due to the problems of eccentricshafts and the supporting point, after the bearing being forcedmeanwhile the mold being pushed forward, because the pushing force willdrive the rotation of the shaft resulting in invalidation of lifting,therefore in the process of lifting, the adjustment shafts are requiredto be adjusted in one direction, and the adjustment range is alsolimited to the axis between the lowest point and the highest point. Ifthe bearing is allowed to be reversed, then under large pressure, theroller will be overall reversely dumped to result in the failure oflifting.

Further, an adjustment dial is provided around the adjustment knob ofthe frame. This technical solution can accurately control the range ofrise and fall by calculating the angle and setting the adjustment scale.

Further, the said mandrel is constituted by the main body portion andthe both end portions; the said main body portion is cylindrical and theboth end portions are smaller in diameter than the main body portion;the bearing mounting portion is provided at the end portions and themain body portion; the said end portions are two-third rounded cylindershaving the mounting holes which are round holes cooperating with thecylinders. This technical solution is intended to allow the roller torun more smoothly and move smoothly by way of lifting of both ends.

Further, the heating device inside the roller is connected with theexternal power source; a rotating carbon brush is provided on the frameand the bearing, and the inner side of the rotary brush is connectedwith the heating device inside the roller while the outer side of therotary brush is connected with the external power source by means of theconnecting wires. The function of hot stamping and other multifunctioncan be achieved by heating the molds with the technical solution abovementioned.
